Title: Method and apparatus for forming a foundations of sand or the like beneath an underwater tunnel
Inventor: JANSZ JOOST WERNER
IPC: E02D23/16
Filed: 1967-12-29
Abstract: 1,234,760. Subaqueous structures; tunnels, suction dredgers and soil stabilization. INTERBETON N.V. 30 Dec., 1968 [29 Dec., 1967; 23 Dec., 1968], Nos. 59169/67 and 61175/68. Headings E1F and E1H. Apparatus for depositing a sand foundation for a subaqueous tunnel 5 has a tower 3 with wheels 4 and rails 2 that pass round the side of the tunnel and carry a flexible pipe-line 1, which includes articulated sections containing pipes A, C primarily for depositing the sand and removing mud and slit, respectively. Each of said sections has a buoyancy tank 10, arms 11, rollers 13 and flexible tubes A', C' therebetween. Adjacent sections are coupled by spindles for the rollers. The buoyancy tank 10a at the free end of the pipe line can be flooded to bring the ends of the pipes A, C into contact with the ground. The tank 10a is blown when necessary by air fed through a pipe (D), Fig. 7 (not shown), in each section. While the pipe-line is being inserted beneath the tunnel water may be pumped through the pipes A to remove obstructions. The pipe line is then retracted while mud and silt are sucked through the pipes A, C. After re-insertion of the pipe line, sand is pumped through the pipe A while the pipe line is retracted and suction is applied to the pipes C to provide an indication of proper sand deposition. Water may be fed through pipes B into branches of the pipe C adjacent the tank 10a, Fig. 8 (not shown), to assist the inward flow thereat. To permit sand deposition beyond the tunnel sides the lower ends of the rails may pivot as indicated in phantom lines. Alternatively, the apparatus has an underwater section 104, Fig. 9, coupled to a floating section 103 by cables 101 and a pipe line 127. A tank 109 housing control equipment and a buoyancy tank can travel along the top of the tunnel 102 on wheels 114 and carries a structure 110 for inserting or withdrawing a pipe line 112, which is basically similar to the pipe line 1. To insert or retract the pipe line a hydraulic piston-and-cylinder unit 124 rocks the structure while remotely-controlled catches 112, 123 on the structure and a post 116 engage alternately with horizontal bars interconnecting pairs of parallel buoyancy-tanks 118, which replace the tanks 10. The pipes A..D are lodged between the tanks 118. The structure 110 and associated mechanism may be mounted on a tower similar to that shown in Fig. 1.

Title: Central buffer coupling for a rail vehicle
IPC: B61G5/08
Filed: 1970-12-29
Abstract: 1368750 Service pipe-lines for automatic central buffer couplings GERMANY MINISTRY OF TRANSPORT 14 Jan 1972 [29 Dec 1970] 61432/71 Heading B7T The valves of service pipe-line couplings of automatic central buffer couplings are actuated by a shaft 16 connected via eccentric 15 and link 14 to a piston 12 held against a spring 13 by a cam 22 ready for a coupling operation. A link 21 pulled by the mating of two buffer couplings pivots a lever 26 to withdraw the cam thus releasing the piston to open the valves. A spring urged lever 24 then moves to engage its projection 32 with a notch 36 in the cam to prevent its re-engagement with the piston on a coupling occurring at high impact. Continued movement of link 21 and lever 26 releases the cam nose 33. On return movement of the lever, a spring-urged plunger 34 can retract to enable the lever to re-engage the can. Shaft 16 can be turned manually, due to the provision of spring plunger 18, to actuate the valves and also to reset the piston in its spring-loaded condition.

Abstract: 717,497. Two-part couplings. COMMERCIAL RADIO-SOUND CORPORATION. March 5, 1951, [March 17, 1950.] No. 5324/51. Class 38(1). [Also in Group XXII] A connector for tapping a high frequency concentric transmission line without distorting the line conductors comprises a metal bracket 38, and block 37 chanelled to receive and clamp the line between them. Holes 44, 45 in block 37 receive a tool to bore holes in the line and expose the outer and inner conductors 33, 34 respectively. A screw 47 is inserted in hole 44 to contact the outer conductor and an insulating bush 48 is inserted in hole 45 inside which a resistor 99 is inserted to contact conductor 33. Bracket 38 has an upwardly extending portion 67 to which is secured a plate 78 carrying a coaxial connector 79 for the branch line. The inner socket contact of said connector carries a bent spring blade 85 which bears resiliently on a cap of the resistor. Bracket 38 also carries a plate 7 1 by which the connector may be mounted in a junction box 74. The end caps of the resistor may be pointed so that where a stranded conductor 33 is employed spring 85 causes the inner cap to penetrate between the strands, Fig. 3 (not shown).

Patent GB-731760-A (GB)
Abstract: 731,760. Moving-coil electrical indicating instruments. RECORD ELECTRICAL CO., Ltd. May 25, 1954 [May 26, 1953], No. 14606/53. Class 37. The core iron or core magnet for the moving coil is secured and accurately positioned by supports which co-operate with a V-groove and rectangular slot in a yoke or other adjacent part of the magnet assembly. In Fig. 1, supports 4, 5 secured to inner magnet 2 register with channel 7 and V-groove 6 respectively in outer yoke 1. The support 4 has a straight face 8 and inclined face 9 within channel 7 and the support 5 has a rounded end in V-groove 6. In the assembly process a gauge of the exact size required is placed in the air gap between arcuate pole pieces 3 and the yoke 1 and the assembly with solder foil between magnet 2 and pole pieces 3 and between magnet 2 and supports 4, 5 is heated until the solder secures the parts together. A spring-loaded screw is used temporarily in place of fixing screw 10. Springs 12 push the pole pieces 3 against the gauge whilst the solder is molten and maintain the exact size of the air gap. When soldering is completed the gauge is removed and fixing non-magnetic screw 10 is inserted through yoke 1 and abuts against inclined face 9 and forces the straight face 8 against corresponding wall of channel 7 and holds the support 5 against V-groove 6. The screw 11 passing through yoke 1 holds the magnet 2 in a definite position. The screw 10 holds the core assembly in the yoke 1 with a three-line contact so that the core assembly may be removed and replaced without losing the original accuracy of location. In a modification, Fig. 3, using segment-shaped pole pieces 3 the V-groove 6 and channel 7 are formed in separate non- magnet members 13, 14. A further arrangement, Fig. 4, uses an external magnet 2 with centre iron or core 1 secured by parts 4 and 5. If desired the rounded support 5 may be cut away between the two screws 11. The parts may be secured together by adhesive instead of solder.
